Fastening device for cables

ABSTRACT

A fastening device for cables includes a fastener and two pivot members. The fastener includes a base body defining a through slot, and a belt extending from the base body. An engaging portion extends from a top wall bounding the through slot. A bottom of the engaging portion defines a number of latching slots. A number of latches are formed on the belt. The belt can be bent, with a distal end of the belt away from the base body extending through the through slot. Thus, the cables are bundled tight between the top of the base body and the belt. The latches engage in the latching slots. The pivot members are pivotably connected to opposite sides of the base body. The pivot members are operable to rotate to force the engaging portion to move up.

BACKGROUND

1. Technical Field

The present disclosure relates to a device for fastening cables.

2. Description of Related Art

Many electronic devices may be connected by several cables to other devices. These cables produce electromagnetic radiation. To test the condition of electro-magnetic interference (EMI) of the electronic devices, the cables are generally positioned at locations where the radiation of the cables is at the highest level. The cables are generally fastened by tapes or cable ties. However, the tapes or ties will not firmly accurately fasten the cables where desired.

DETAILED DESCRIPTION

The disclosure, including the accompanying drawings, is illustrated by way of example and not by way of limitation. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.

FIGS. 1, 3, and 4 show an exemplary embodiment of a fastening device for cables 50 including a fastener 20 and two pivot members 30.

The fastener 20 includes a rectangular base body 21 and a long belt 22 extending forward from a front side of a top of the base body 21. A through slot 23 is defined in the base body 21, extending through the front and rear side surfaces of the base body 21. An engaging portion 24 slantingly extends downward and forward from a rear side of a top wall 232 bounding the through slot 23. A plurality of latching slots 241 is defined in a bottom surface of the engaging portion 24, arranged in a fore-and-aft direction. A front side surface 242 bounding each latching slot 241 is slanting forward and down. A rear side surface 243 bounding each latching slot 241 is substantially perpendicular to the top wall 232. Two substantially rectangular through holes 25 are respectively defined in left and right sides of the base body 21. Two pivot holes 252 are respectively defined in front and rear sidewalls 251 bounding each through hole 25. A plurality of suction cups 26 is attached to a bottom of the base body 21. A recess 27 is longitudinally defined in a top surface of the belt 22. The width of the recess 27 is the same as the width of the engaging portion 24. A plurality of latches 28 extends up from a bottom wall 271 of the recess 27, arranged in a row along the lengthwise direction of the belt 22. Each latch 28 is substantially wedge-shaped. A slanting guiding surface 281 is formed on a front side of each latch 28.

Each pivot member 30 includes a pivot tab 31 and two pins 32 respectively extending from opposite sides of the pivot tab 31.

Referring to FIGS. 1 and 2, in assembly, the pivot members 30 are inserted in the corresponding through holes 25, to allow the pins 32 to engage in the corresponding pivot holes 252. The pivot tabs 31 respectively abut against opposite ends of a top surface bounding the front latching slot 241 adjacent to the front end of the engaging portion 24.

FIG. 5 shows in use, the base body 21 is fastened to a desktop by the suction cups 26. The cables 50 are placed on the top surface of the base body 21. The belt 22 is bent to bind the cables 50 together with the top surface of the base body 21. A distal end of the belt 22 away from the base body 21 is inserted into the through slot 23 from a rear side surface of the base body 21. The belt 22 is slid along the bottom of the engaging portion 24, and is pulled out of the front side surface of the base body 21. The distal end of the belt 22 is further pulled forward, until the cables 50 are bundled tight between the top surface of the base body 21 and the belt 22.

When the belt 22 is slid along the engaging portion 24, a lower portion of the engaging portion 24 is received in the recess 27. Parts of the latches 28 engage with the corresponding latching slots 241 guided by the guiding surfaces 281, and disengage from the latching slots 241 guided by the front side surfaces 242. If the belt 22 is pulled back along the engaging portion 24, the latches 28 are blocked by the rear side surfaces 243, which means the belt 22 cannot be slid back along the engaging portion 24. Therefore, the belt 22 will not loosen after the cables 50 are bundled tight.

To release the cables 50, the pivot members 30 are rotated, to allow the pivot tabs 31 to drive the engaging portion 24 to move up. The latches 28 disengage from the latching slots 241. The belt 22 can be slid back in the through slot 23.

Even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and the functions of the embodiments, the disclosure is illustrative only, and changes may be made in details, especially in the matters of shape, size, and arrangement of parts within the principles of the embodiments to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
